Is there a seperate fuse for the rear speakers on my park avenue? Not an Ultra Thanks

not likely, you have both the rears go out at once?

Did youuse the stereo **** for balance setting front /rear?

yes, both speakers are out. And yes I tried to adjust the fader. Only the front working. Thanks for the replies.

Sounds like your rear channel blew out on the deck, that or something is somehow shorting that channel out.
Were you listening to it when they stopped working?

Do you have a multimeter?
If so set it to ohms, disconnect the speakers wiring connector, then check the two speakers leads, if it says OL or 0, then your speakers coil is blown, considering both went at the same time my money is on the decks real channel.

I just bought the car and they were like that. I will check into a multimeter. Thanks

You can get a decent multimeter for about 15-20$ on amazon.
You are very welcome.

Here is the one I got, it does not come with the alligator clips you will use a good bit, but they are only a few bucks more.

Here is the one I bought a while back, great meter for 20.00

If you get that I'd get these with it.

If you end up finding out the channels are blown, and you want to replace it I may be able to help you find what you need.
I'd get a good aftermarket deck if it were me, unless I wanted to keep that original look.

For about the same price, he could goto Walmart or Autozone to get a DMM.

Yeah, I'd go there first, I'm just so used to finding things online since I have Amazon Prime, good post Mike.

I'm a firm believer in buying things local. I have a mom&pop hardware store 3 blocks away from me. Though the prices are slightly higher than Lowes or Walmart(which is 6 miles away) I'd rather buy from the local guy. Plus, the owner is wayyyy more friendlier than the corporate required people greeter at china-mart and Blowes.
